Had a chance to check through the world of WoT book and i cant see any mention of how many nym there were. The book mentions them in the same breath as Ogier and Aeil. Cant remember if it is said in EotW or somewhere else in the books.

hey long time lurker, but doing a re-read in prep for A Memory of Light gave me something to actually add. It concerns "normal" channellers being able to grab souls. There was a mention in LoC that Sammael had a game called Zharra (sp?) and its "once human playing pieces" with him in Illian. It was noted that it would have belonged to a darkfriend so it might not have been an acceptable practice during the Age of Legends, but placing a soul in something was obviously doable. I feel like the cour'souva and even myrdrall blades are more or less something that the DO is involved with, but I can't imagine him being bothered with something as petty as board game.

Another thing that just struck me was whether or not the ability to place souls into something, be it construct or Zharra pieces, might have been a Talent, not something inherently achievable by Aes Sedai?
